Details

Featuring 44 in-lbs. of peak torque and a 21-position clutch with auto shut-off, the new screwdriver offers improved torque control during repetitive applications. Two speeds (0 - 200 RPM / 0 - 600 RPM) offer further user control for precision work and at only 9.6 in. in length and under one pound, the M4 Screwdriver is easy to use with one hand, featuring a 1/4 in. quick-change chuck for one-handed bit changes.Drilling more than 200 holes per change, the M4 Screwdriver is the first tool to feature Milwaukee's RedLithium 2.0 Ah battery on the new M4 platform, offering up to 50% more runtime.

This is similar to one I had ten years ago. However this is much more expensive. The battery life is ok, could be longer since it is LIO and not nicd. Simple to use variable torque is nice but wasted on a unit this small.

Had to remove and then re-install multiple screws from a panel. Tool performed flawlessly and efficiently. I really enjoy the battery level meter in the handle! I look forward to abusing this tool some more in the future. It's Milwaukee tough!

Very convenient for installing door and cabinet hardware, electrical switches, outlets and plates. This is a replacement for a similar Milwauked screwdriver that I have used for over 10 years (and it's still working)

This little jigsaw performs "above it's weight," as they say. I thought it would be a good purchase to have just in case - now I'm wondering if I can dump my corded jigsaws! It has sufficient weight to cut cleanly and solidly in just about any material. It doesn't have a pneumatic sawdust clearance system, or occilator, but I lived without those things before. The trigger action is smooth and positive, the saw moves over the surface smoothly and easily, and the design allows one- or two-handed operation. In short, it's a keeper! And buying reconditioned from CPO was a BIG bonus!

This is an update of the Milwaukee 4v screwdriver without the rubber overmold. That means it's a solid performer for the smaller tasks, with slower speeds for precision screw driving and a redesigned battery and charger. The 2-way handle - straight or pistol-grip - is a plus. The battery charges in an hour or less, and seems to have very decent life, although I don't have any numbers to back that up. The unit feels solid and is a pleasure to use. Granted, you won't be driving #10 screws without a pilot hole with this thing, but that's not what it's meant for. For most average work, though, it can be a star. For woodworkers, this thing can be a great teammate to your drill.

Ahh, good ole Milwaukee power tools. I got this little beauty as a companion to their M12 Fuel Impact Driver. I use this for very sensitive applications like electronic work, and the Impact for everything else.

When I first took it out of its box, I was surprised with how small it was. The ergonomics are pretty good for it just being basically a 10 inch long shaft. The rubber on the tool feels good on the hands. The transition from it's "Straight" grip to it's "Pistol" grip feels very smooth and feels like it wont go from one to the next on accident while working.

The Battery light indicator is a definite plus to the tool as well. I also really dig the forward clutch, as when it's activated the tool just stops instead of making that annoying clicking noise that most clutch systems do.

This tool has around 40 pounds of torque and 21 clutch setting with about 2 pounds at it's first.

Suffice it to say this thing wont be driving deck screws any time soon. This particular tool was designed with electricians, Computer Tech's, and just regular home owners in mind. I personally find this tool very useful for building computers in my shop.

Overall, I would highly recommend this tool for anybody who wants a good, lightweight, low torque, and very precision oriented tool to preform lightweight and sensitive tasks in their shop.

It`s a good tool. The "BUT" is it`s larger and somewhat clumsy compared to the original. The charger feels flimsy and at times takes a little finesse before it accepts the battery. Still it is handier and easier to carry than the pistol shaped drivers.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.

Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.

Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).

Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
